p FFllQ GEORGE A. GASPERS AND NATHANIEL S. DEU'ISGH, OF NEW YORK, 1\T.Y.

MILK-BOTTLE CAP.

Application filed December 23, 1914, Serial No. 878,757.

To all whom it may concern:

Be it known that we, GEORGE A. CAsrERs and NATHANIEL S. DEUTSGH, citizens of the United States, residing at New York, in the counties of New York and Bronx, respec tively, and State of New York, have invented a new and useful Milk-Bottle Cap, of which the following is a full, clear, and exact specification.

This invention relates to caps for milk bottles, and has for its object to allow for the'expansion of the milk when it congeals or freezes without danger of breaking the bottle or exposing the projected portion of the frozen mass to the outside air laden with dirt and germs.

A further object is to provide a cap for this purpose which may be easily applied the upper end portion or neck of a milk bottle having our improved cap applied thereto, the upper extremity of the bottle neck and the cap being shown in section to better illustrate the construction of the latter. Fig. 2 is a similar view showing the position of the cap when the milk freezes and projects itself above the mouth of the bottle, and Fig. 3 is a detailed perspective view of one means for holding the cap in position upon the neck of the bottle.

The milk bottle A illustrated in the drawings is of the ordinary type'and form, having a bead (1 around its mouth, and an 1nternal shoulder or seat a for the usual closure or disk.

Our improved cap B consists ofa disk 5 similar to those now generally in use, and in addition to said disk a depending skirt portion, the lower end I) of which is secured around the mouth of the bottle below the Specification of Letters Patent.

Renewed November 4, 1915. Serial No. 59,694.

of a metal band C, best illustrated in Fig. 3,

having an interlocking tongue 0, or by any other suitable holding means adapted to retain the lower end portion b of the cap around the neck of the bottle below the bead a. The disk I) is inserted in the mouth of the bottle so as to rest upon the seat a when the bottle is filled, as shown in Fig. 1. If the milk freezes and projects itself above the top of the bottle, the disk I) will be displaced and raised upon the top of the frozen projecting portion and as said disk is thus raised, the accordion plaiting b will open up or expand, as illustrated in Fig. 2. The frozen projecting portion will thus be inclosed and protected by the cap against contamination.

Having thus described our invention what we claim as new and desire to secure by Letters Patent of the United States is 1. A bottle cap having a horizontally plaited skirt portion the lower end of which is adapted to be secured around the neck of a bottle, the plaits permitting vertical expansion of the skirt portion without movement of the part secured around the bottle neck.

2. A bottlecap having a disk to fit in the neck of a bottle, and a horizontally plaited skirt portion to be secured around the bottle. neck, the plaits permitting vertical expansion of the skirt portion without movement of the parts secured around the bottle neck.
